Project Summary: The main objective of this study is to investigate how river ice affects the flow characteristics of sediment transport, velocity profiles, and secondary flow patterns (such as circulations and vortexes). The main objective is to understand how the flow changes when the surface is frozen and during the melting period, and how it may be affected by climate change-related reductions in river ice duration. To do this, the researchers will collect measurements using multiple sensor devices during winter seasons in a meandering section of the Red River in Fargo, ND. These sensors will monitor the velocity and discharge of the river, and the collected data will be processed using advanced analytical methods. By gaining insights into the effects of river ice on flow characteristics, the study will contribute to the development of new theories about river ice and its impact on bank erosion processes during spring floods.
